Conversion fork TPH PX


I want to know if I can fit a TPH steering column Nr.50401100 or 504011000 to my 200PX -86? I have wide tyres 130/70.

I want a fully hydraulic discbrake in front, but do my PX rims fit? How do I fit a headcylinder on the steering, were do I put the light switches? And what parts doesnt come with the TPH fork?

Can I add a rear discbreak with 130/70?
